I applied via Campus Placement and was interviewed in Dec 2022. There were 3 interview rounds.
First 20 question for apti and then coding round of 20 questions each from c/c++ , java and SQL
(5 Questions)
- Q1. OOPS questions Data structure like linked list Binary search SQL
- Q2. Is multiple inheritance allowed in java?
- Ans.
No, multiple inheritance is not allowed in Java.
Java does not support multiple inheritance for classes to avoid the diamond problem.
However, multiple inheritance is allowed for interfaces in Java.
Example: class A extends B, C is not allowed, but interface A extends B, C is allowed.
- Q3. What is inheritance
- Ans.
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Allows a class to inherit attributes and methods from another class
Promotes code reusability and reduces redundancy
Creates a parent-child relationship between classes
Example: Class 'Car' can inherit properties and methods from class 'Vehicle'
- Q4. What is real time example of polymorphism
- Ans.
Polymorphism in software development is like a person driving different vehicles using the same driving skills.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
For example, a superclass 'Shape' can have subclasses like 'Circle' and 'Rectangle' which can be treated as 'Shape' objects.
Calling a method like 'draw()' on a 'Shape' object will execute the specific implementatio...
- Q5. What is your project based on?

Interview Questionnaire
6 Questions
- Q1. Code to print * in five consecutive lines
- Ans.
Code to print * in five consecutive lines
Use a loop to iterate five times
Inside the loop, print a string containing a single * character
- Q2. A ball is left from a height of 10 meters. After bouncing first time it looses 10% of its previous height the next time it bounces. Write a code to calculate the number of bounces the ball goes through unt...
- Ans.
Code to calculate number of bounces a ball goes through until it comes to rest.
Use a loop to simulate the bounces until the ball stops bouncing
Calculate the height of each bounce using the given formula
Keep track of the number of bounces in a counter variable
- Q3. Which is the best and less time consuming way to calculate factorial of a number?
- Ans.
The best and less time consuming way to calculate factorial of a number is using iterative approach.
Iteratively multiply the number with all the numbers from 1 to the given number
Start with a result variable initialized to 1
Multiply the result with each number in the range
Return the final result
- Q4. Write the code to find factorial using function recursion.
- Ans.
Code to find factorial using function recursion
Define a function that takes an integer as input
Check if the input is 0 or 1, return 1 in that case
Otherwise, call the function recursively with input-1 and multiply it with the input
- Q5. They asked for my introduction.
- Q6. They asked about my family members.
Interview Preparation Tips
Experience: Aptitude test was moderately tough. The coding test was on basics of c language of all the topics.
Tips: Solving R. S. Agrawal for Aptitude and videos on YouTube on C language are sufficient to score well.
Duration: 1 hour
Total Questions: 60
Round: Technical Interview
Experience: I wrote the first code correctly. I wrote the second code 75% correct and they explained me my mistakes and I could understand where I was going wrong then I corrected my code and then they were satisfied. They asked me whether I could write the factorial code by function recursion method. I replied that I can write the factorial code but not by function recursion method. They were satisfied.
Tips: Build your coding skills by more practice.
Round: HR Interview
Experience: In this round they just asked me my introduction and said that you are shortlisted for now but we will give you final confirmation after a week.
Tips: Don't lie. Be genuine.

- Q1. What is inheritance?
- Ans.
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
Allows a class to reuse code from another class
Creates a parent-child relationship between classes
Derived class inherits attributes and methods from base class
- Q2. What is oop principles?
- Ans.
OOP principles are the fundamental concepts of object-oriented programming that help in designing and implementing software solutions.
Encapsulation: Bundling data and methods that operate on the data into a single unit (class).
Inheritance: Allowing a class to inherit properties and behavior from another class.
Polymorphism: The ability of objects to take on multiple forms or have multiple behaviors.
Abstraction: Hiding t...
- Q3. What is polymorphism principle?
- Ans.
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or objects.
Examples include method overloading and method overriding in object-oriented programming languages like Java.
(1 Question)
- Q1. Internal working of Hash Map
- Ans.
Hash Map is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hash Map uses a hash function to determine the index of the key-value pair in the underlying array.
Collisions can occur when multiple keys hash to the same index, which can be resolved using techniques like chaining or open addressing.
Hash Map typically has a load factor threshold to determine whe...
